The Theory of Continental Drift

• Evidence from landforms- features on different continents match or line up
• Evidence from fossils- similar fossils have been found on opposite sides of oceans
• Evidence from climate- fossils show that climates were different in the past, possibly because the continent moved.

Scientists Reject Wegener's Theory

• He could not provide a satisfactory explaination for the force that pushes or pulls the continents.
